用maven时出现，报错 miss 一些包，可是发现项目里已经引入了，但仍是报错

引用一个解决方法：

解决方法： If you are using Eclipse, Right Click on your Project -> Maven -> Update Project. It will open Update Maven Project dialog box.

In that dialog box, check Force Update of Snapshots/Releases checkbox & click OK. (Please refer image below)

Update Maven Project Dialog Box

This worked for me !
